Understanding the nature of bullies and bullying is of considerable theoret
ical and practical importance. We offer a commentary on a recent debate on
this topic between Sutton, Smith, and Swettenham (1999a, 1999b) and Crick a
nd Dodge (1999). In this commentary, we first summarize the main points of
the debate, including alternative views of bullies as social inadequates Ve
rsus Machiavellian schemers. Then we clarify some unresolved issues concern
ing the nature and limits of social competence and the roles of values in b
oth social competence and in bullying. Finally, it is argued that variation
s in children's emotion processes, such as emotionality and emotion regulat
ion, also may underlie some of the individual differences that have been fo
und in empathy, social information processing, and in reactive ('hot-headed
') and proactive ('cold-blooded') aggressive and bullying patterns.
